ok every one has seen where they said a robot dino would be to hard to explain but we can have a 20ft scorpion aka "scorponok"????? :lol so why cant we have a trex? also in the TF2 trailer i think its a Insecticon that sam pulls the head off of, second we can also have Ravage! every one here knows that is him on the beach
Grimlock, Slag, sludge, snarl, and swoop cant be that hard to explain..
